Question

in a certain test, there is a multiple choice question with the possible answers a, b, c, d, and e. by randomly guessing, the chances of getting the correct answer are stated as 1 in 5. express the indicated degree of likelihood as a probability value between 0 and 1 inclusive

the probability is
(round to three decimal places as needed.)

Explanation:

Step1: Understand the probability

The chance of getting the correct answer is "1 in 5", which means the number of favorable outcomes (correct answer) is 1, and the number of total possible outcomes (all answer choices) is 5.

Step2: Calculate the probability

Probability is calculated as the number of favorable outcomes divided by the number of total possible outcomes. So the probability $P = \frac{1}{5}$.

Step3: Convert to decimal

$\frac{1}{5} = 0.2$ (and since we need to round to three decimal places, it remains 0.200 as 0.2 is equivalent to 0.200 when rounded to three decimal places).

Answer:

0.200
